Celebrate 50 issues of Sonic Universe and 20 years of Sonic the Hedgehog comics with this double-sized anniversary spectacular! Metal Sonic has been one of Dr. Eggman's deadliest creations. But what happens when the fastest robot around has to track down... itself? It's a clash of metallic titans as Metal Sonic is sent to take down his original model -- now known as the Secret Freedom Fighter Shard! All this plus a special bonus presentation of the very first race between Sonic and Metal Sonic! Featuring a brand-new, bone-chilling cover from Sonic artist supreme Patrick "SPAZ" Spaziante.
